Announcement: New Dec2023-SP1 Bugfix release of MonetDB suite
by Sjoerd Mullender 18 Mar '24

18 Mar '24

The MonetDB Foundation is pleased to announce the Dec2023-SP1 bugfix release of the MonetDB suite of programs. More information about MonetDB can be found on our website at <https://www.monetdb.org/>. For details on this release, please see the release notes at <https://www.monetdb.org/release-notes/dec2023/>. As usual, the download location is <https://www.monetdb.org/downloads/>. ### - The copyright for the MonetDB software has been transferred to the newly established MonetDB Foundation, a not-for-profit foundation with the express goal of furthering the MonetDB database system. The license for the software does not change: MonetDB remains fully open source. ### Client Package - Fixed an issue where mclient wouldn't exit if the server it had connected to exited for whatever reason while the client was waiting for a query result. ### MonetDB Common - The internal hash function for floating point types has been changed. It is now no longer based on the bit representation, but on the value, meaning that +0 and -0 (yes, they both exist in floating point) now hash to the same value. - Fixed a regression where bats weren't always cleaned up when they weren't needed anymore. In particular, after a DELETE FROM table query without a WHERE clause (which deletes all rows from the table), the bats for the table get replaced by new ones, and the old, now unused, bats weren't removed from the database. ### Geom Module - We switched over to using the reentrant interface of the geos library. This fixed a number of bugs that would occur sporadically. ### SQL Frontend - performance improvement of 'startswith' and 'endswith' filter functions for join operators - The function json.isvalid(json) incorrectly returned true if the argument was null. It should return null. ### Bug Fixes - [6800](https://github.com/MonetDB/MonetDB/issues/6800): Please add information_schema (ANSI SQL norm) - [7152](https://github.com/MonetDB/MonetDB/issues/7152): Occasional dbfarm corruption upon database restart - [7390](https://github.com/MonetDB/MonetDB/issues/7390): Some MonetDB Server crashes found - [7412](https://github.com/MonetDB/MonetDB/issues/7412): MonetDB server crashes in `vscanf` - [7415](https://github.com/MonetDB/MonetDB/issues/7415): MonetDB server crashes in `HEAP_malloc` - [7416](https://github.com/MonetDB/MonetDB/issues/7416): MonetDB server crashes in `atom_get_int` - [7417](https://github.com/MonetDB/MonetDB/issues/7417): MonetDB server crashes in `trimchars`. - [7418](https://github.com/MonetDB/MonetDB/issues/7418): MonetDB server crashes in `bind_col_exp` - [7420](https://github.com/MonetDB/MonetDB/issues/7420): Performance issue with lower(string) - [7425](https://github.com/MonetDB/MonetDB/issues/7425): The last statement, execution error, is a false positive? - [7426](https://github.com/MonetDB/MonetDB/issues/7426): Unexpected result for INNER JOIN with IS NOT NULL - [7428](https://github.com/MonetDB/MonetDB/issues/7428): Unexpected result when using BETWEEN operator - [7429](https://github.com/MonetDB/MonetDB/issues/7429): Unexpected result when using `CASE WHEN` - [7430](https://github.com/MonetDB/MonetDB/issues/7430): Unexpected result when using `AND` and `IS NOT NULL` - [7431](https://github.com/MonetDB/MonetDB/issues/7431): [bug] Error code found, please confirm - [7432](https://github.com/MonetDB/MonetDB/issues/7432): MonetDB server crashes in `dameraulevenshtein` - [7433](https://github.com/MonetDB/MonetDB/issues/7433): MonetDB server crashes in `exp_atom` - [7434](https://github.com/MonetDB/MonetDB/issues/7434): MonetDB server crashes in `exp_bin` - [7435](https://github.com/MonetDB/MonetDB/issues/7435): MonetDB server crashes in `exp_copy` - [7436](https://github.com/MonetDB/MonetDB/issues/7436): MonetDB server crashes in `exp_ref` - [7437](https://github.com/MonetDB/MonetDB/issues/7437): MonetDB server crashes in `exp_values_set_supertype` - [7438](https://github.com/MonetDB/MonetDB/issues/7438): MonetDB server crashes in `exps_bind_column` - [7439](https://github.com/MonetDB/MonetDB/issues/7439): MonetDB server crashes in `exps_card` - [7440](https://github.com/MonetDB/MonetDB/issues/7440): MonetDB server crashes in `gc_col` - [7441](https://github.com/MonetDB/MonetDB/issues/7441): MonetDB server crashes in `is_column_unique` - [7442](https://github.com/MonetDB/MonetDB/issues/7442): MonetDB server crashes in `mat_join2` - [7443](https://github.com/MonetDB/MonetDB/issues/7443): MonetDB server crashes in `merge_table_prune_and_unionize` - [7444](https://github.com/MonetDB/MonetDB/issues/7444): [bug] the table cannot be created because the reserved word is incorrectly set - [7447](https://github.com/MonetDB/MonetDB/issues/7447): Unexpected result when using `BETWEEN` in `INNER JOIN` - [7448](https://github.com/MonetDB/MonetDB/issues/7448): Unexpected result when using `AND`/`OR` chain - [7450](https://github.com/MonetDB/MonetDB/issues/7450): Unexpected result when `CREATE VIEW` with `WHERE NULL` - [7451](https://github.com/MonetDB/MonetDB/issues/7451): Unexpected result when using `BETWEEN` and `CAST` - [7453](https://github.com/MonetDB/MonetDB/issues/7453): Cannot recover an msqldump - [7455](https://github.com/MonetDB/MonetDB/issues/7455): Unexpected result when using `BETWEEN` with `BOOLEAN` values - [7456](https://github.com/MonetDB/MonetDB/issues/7456): Crash when `INNER JOIN` with `VIEW` - [7457](https://github.com/MonetDB/MonetDB/issues/7457): Unexpected result when using `AND` with `INTEGER` - [7458](https://github.com/MonetDB/MonetDB/issues/7458): Unexpected result when using `SIGN` - [7461](https://github.com/MonetDB/MonetDB/issues/7461): Crash by potentially use of bad escape characters - [7462](https://github.com/MonetDB/MonetDB/issues/7462): Crash when using `BETWEEN AND` - [7465](https://github.com/MonetDB/MonetDB/issues/7465): Unexpected result when using `NULL` in `BETWEEN`
